Field Activity 2023-637-FA

Identifier 2023-637-FA
Alternate names Esther Lake, AK 2023
Purpose Survey of Esther Lake, Alaska to investigate paleoseismic record of large magnitude earthquakes associated with the Alaskan-Aleutian plate boundary.
Location Esther Lake, Prince William Sound, Alaska
Summary Field activity 2023-637-FA was successful. A grid of sub-bottom profiles and bathymetric data was collected over most of the lake. Sediment Gravity cores recover sediment from the top 2 meters of lake bottom.
Info derived Bathymetric map, high-resolution sub-bottom profiles, and ~2 m gravity cores.
